Hi, I am returning to the hobby after a 10 year absence. My husband has never had fish, but has picked it up very quickly. We have a lot of different temperments. At first they were all together now we have Split them. We have all of the aggressive in 1 tank, 2 jaguar, 2 dempseys, and 3 green terrors. We keep reading about how mean the jags and terrors can be but the female dempsey runs the tank. I have never had any of them before. I am wondering if as they grow will they become the nasty fish I. Keep reading about? Befor we moved fish around a female. Blood parrot ran the tank. They are so sweet now. Thanks for reading
